Aijiren - 20mm Crimp Headspace Vial
Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial. The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Headspace Vials suitable for headspace analysis of volatile solids and gases.
